The W2K problem was a piece of cake. Here it comes the I4 one:
[..]GoogleWatch has an interesting theory: When programming Google, they used standard 32-bit integers to identify pages. 32-bit integers allow you to count up to 4.2 billion, and Google is pretty close to that many pages. It's going to be tricky to upgrade all 15,000 machines to use a larger size integer at once, so maybe this is the reason Google has been having problems lately. [Google Weblog]
